WILLIAM T. OARROLL, OE wooNsOOxET, RHODE ISLAND, AssIGNOR To SIMEON S.COOK,

OF SAME PLACE.

Specification forming part of Letters Patent No. 144,601, dated November18, 1873 application filed September 8, 1873.

To all whom t may concern.'

Be it known that I, WILLIAM T. CARROLL, of Woonsocket, in the county ofProvidence and State of Rhode Island, have invented certain Improvementsin Spindles, of which the following is a speciiication:

Figure 1 is a central vertical section of the invention.

The present invention relates to certain new and useful improvements inspindles, having for its obj ect the construction of a spindle which islight, durable, conveniently lubricated, and operated with less powerand at greater velocity than the spindles ordinarily in use.

My invention consists in an auxiliary spindle operatin g in combinationwith the main spin- I dle and bolster, substantially as hereinafterspecified.-

In the drawing, a represents the top of a slender tapering spindle,formed with a projecting tapering base, b, having near its bottom aWhirl, k, and fitting over a stem, f, of a bolster, o. The stemf isformed With a bore, and contains an auxiliary loose spindle, a, thatturns in a seat or bearing, n, formed in the upper portion of thebolster o. The top of the auxiliary spindle a forms a seat or bearingfor the upper portion of the base b,

which revolves on it, as well as on the top ofthe stem f. Alubricating-passage is formed between the auxiliary spindle a and theinterior of the stem f, consisting of an orice, h, which is suppliedwith a wooden or other plug, through which the oil percolates, thuslubricating the desired portions of the spindle. By means of theauxiliary spindle a, the friction of the main spindle is greatlylessened, and therefore can be operated with greater facility thanheretofore.

By diminishing the diameter of the upper portion a of the spindle, andextending it in a tapering form, so as to securely hold and al- Vlow forthe wear of the bobbin, which is revolved with it, the weight of thespindle is decreased, and the friction caused by the bob- Y binrevolvingon the top bearing of a dead spindle is entirely overcome. Besides,abobbin revolving on a dead spindle soon has a hole worn in its top,which prevents its running steadily 3 but in my improvement the bobbinis tightly fitted on a live spindle that revolves with it, therebyobviating this 'objection.

greater part of the spindle above the top rail l ofthe frame, one railof the machine may be dispensed with, the height of the .spindle isshortened, and its Weight, which in ordinary ring spinning-spindles isabout twelve ounces,

is, by the present arrangement, reduced to three ounces and thereforerequires less power to operate it.

Havingl thus fully described my improvements, what I claim as myinvention, and desire to have secured to me by Letters Patent, is-

The auxiliary spindle a, operating in the socket or stem f on the seatn, and forming a seat or bearing for the base b of the spindle a.,substantially as specified.

In testimony whereof I have signed my name to this specification in thepresence of two subscribin g witnesses.

WILLIAM T. CARROLL.
